 And when those individuals would reach out to other individuals, the FBI would watch those people and the innocuous ones they'd let go and the suspicious ones they'd study. And they built a web of contacts between the eight men with ties to ISIS to the people they were talking to and the people those people were talking to to see what was planning. They followed them around the Internet. They followed them around town. They monitored their communications. They spied on them without these people knowing they were being spied upon. We hope.
